ADSL Splitter<br />
ADSL Splitter Series<br />
ALS-10-EU/I<br />
ADSL ISDN Splitter<br />
The ALS-10-EU/I is a low-cost, compact, designed to implement the functionality of<br />
low pass filter in ISDN-BA with 2B1Q or 4B3T baseband linecodes over ADSL<br />
application. It integrates low pass filters that block the high frequency energy from<br />
reaching the ISDN-BA device and provide isolation from impedance effects of the<br />
ISDN-BA device on ADSL. Because the ISDN splitter connects directly to the<br />
subscriber loop media, it must also provide some protection for externally induced<br />
line hits or faults which could damage any attached equipment or endanger humans<br />
interacting with the installed equipment.<br />
Features Specifications<br />
Consists exclusively of all passive components<br />
Designed for implementation of ADSL CPE application<br />
Handles all ISTN loop current from 0 to 60 mA<br />
If the power supply or ATU-C/ATU-R fails, telephone service on<br />
the ADSL line will operate normally<br />
Provides excellent isolation between DSL and ISDN<br />
Application<br />
The circuit protection will be provided mostly by standard central office line protection<br />
means and additional protection measures built into splitter to protect against line<br />
overstress which could damage the splitter itself. The electrical and transmission<br />
specification is based on ETSI TS 101 952-1-3 V1.1.1 for ISDN-BA requirements.<br />
